Does a polygon have four sides?

Answer: Yes it can have four sides, but as the explanation below shows, it can have many other numbers of sides as well. Explanation: A polygon can have as many sides as needed. We give specific names to polygons dependent upon the number of sides that it has: triangle: A polygon made with three sides. quadrilateral: A polygon made with four sides. pentagon: A polygon made with five sides. hexagon: A polygon made with six sides. heptagon: A polygon made with seven sides. octagon: A polygon made with eight sides . In fact, if we have n sides, we can call that polygon an n-gon. So in short, yes a polygon can have four sides, so all 4 sided shapes are polygons, however, not all polygons have four sides.
